ACTIVE SULFUR-FREE FUNCTIONAL SILANES FOR SILICA COMPOUNDS

Title:

ACTIVE SULFUR-FREE FUNCTIONAL SILANES FOR SILICA COMPOUNDS

Document Type and Number:

Japanese Patent JP2023088314

Kind Code:

A

Abstract:

To provide sulfur-vulcanizable rubber compounds and coupling agents for incorporating silica fillers into polymer compositions.SOLUTION: A sulfur-vulcanizable rubber compound comprises a silane functionalized diene elastomer, a silane coupling agent, and a silica filler. The silane coupling agent does not comprise an active sulfur moiety. The rubber compound is a reaction product of a siloxyl condensation reaction between the silane functionalized diene elastomer and the sulfur-free silane coupling agent. The coupling agent comprises at least one end group reactive with a hydroxyl group contained in the silica filler and a silane moiety contained in a diene-based elastomer.SELECTED DRAWING: Figure 2
